Our high-pressure flange range is suitable for industrial piping systems where the selected flange class, material and configuration are specified for elevated pressure and temperature service.
High Pressure Flange Classes
Class 900 Flanges
Class 900 Flanges are used in high-pressure piping systems where the applicable piping standard specifies this pressure class. They are available in Weld Neck, Blind, Slip-On and other configurations depending on size and standard.
Class 1500 Flanges
Class 1500 Flanges are designed for more demanding pressure applications and are commonly specified in critical industrial piping, refinery and process systems.
Class 2500 Flanges
Class 2500 Flanges are among the higher pressure classes covered by ASME B16.5. They are used where the piping design requires the applicable high-pressure flange rating.
Actual pressure-temperature capability depends on material, size, temperature and the applicable rating standard.
